One thing I've learned on any site that offers coupons, is not to sign up. What I saw from retailmenot.com was I just did a google search on the name of the retailer (ie Johnny's)followed by the word coupon. When I clicked on the link for retailmenot.com, the coupon and the code appeared. I just wrote down the code and applied it.
Can they track IP addresses?
I don't know if they do or not on any of the sites. Have you set your Google Web History to "pause" if your using google?
Johnny's is one of my favoriite sites to browse but not always buy
